Electronics is the manipulation of electrical current or electromagnetic fields by the use of electrical current or electromagnetic fields. The purpose of the manipulation is to use the current as a signal, carrying information. Ordinarily either the voltage or ampage of the current is varied with some kind of input to create the signal. The field was formerly known as radio electronics and was a minor speciality within the field of electrical engineering, centered on the study of the vacuum tube. |
